水压致裂地应力测量在福宁高速公路赤岭隧道工程中的应用

Application of Geostatic Stress Measurements by Hydraulic Splitting to Chiling Tunnel, Xiapu, Fujian Province

福建霞浦赤岭隧道工程通过钻孔内水压致裂原地应力测量 ,获得了隧道区地应力的大小、方向及岩石的抗拉强度等力学参数 。

Basing on geostatic stress measurements by hydraulic splitting in Chiling Tunnel, Xiapu, Fujian Province, some mechanical parameters such as geostatic stress magnitude, geostatic stress direction and tensile strength of rock, etc. have been obtained, which are the important bases for tunnel design.
